The novel first appeared in the United States from Delacorte Press, New York, in 1966. The first British edition is the Victor Gollancz hardback of August 1966, 216 pages, issued before ISBNs and numbered in the Gollancz SF series. Gollancz reissued it in 1985 in hardback (ISBN 0 575 03705 9, priced £8.95, also 216 pages), so a decimal price or an ISBN means the reissue, not the first. Pan published the first UK paperback in 1973 and Grafton a further paperback in 1986.
An older Gollancz first edition is identified by what is missing: later impressions are recorded on the back of the title page, so a copy with no impression line under its first-publication date is the first.
Allen and Patricia Ahearn's publisher list for ILAB says Gollancz made no first edition statement but noted subsequent printings, in the form "First published (year)" followed by "Second impression (year)". Dealers' listings show the same pattern. Two separate sellers of the 1948 reprint of Dilwyn Rees's The Cambridge Murders quote "Second impression (first cheap edition) January 1948" on the verso, one adding that "First published October 1945" is also stated, while the 1945 printing is offered simply as the first edition.
Read the full guide to Gollancz first editions, decade by decade, and check your copy's copyright page against it. Our number line decoder reads the printing from the row of numbers.
We have not yet confirmed the issue points that tell this first impression from later ones. Until we do, compare your copy's title page and copyright page with the publisher, place and year above: any later printing or edition statement means it is not this one.
